Exemplary embodiment according to the present invention, each element of 160 control input location detecting apparatus 100 of controller it
Between signal processing and electric energy supply operation, to detect the coordinate of input position.Controller 160 is based in touch sensor
The electric signal detected on 145 determines the type of the input method on touch-screen and input position.
More particularly, controller 160 detects hand by the change of the intensity of the electric signal received in receiving unit 141
Refer to touch input.
If there is no finger touch input, then the intensity of internal signal is kept constant, this is because according to controller 160
Control, be supplied to by wave filter 150 from power supply unit 130 transmitting element 143 electric energy intensity have preset value.
If there is finger touch input, then the uniform electric field formed between transmitting element 143 and receiving unit 141 leads to
Cross finger part leakage.That is, a small amount of charge is attracted to the point of contact.Positioned at the every nook and cranny of panel circuit measuring charge simultaneously

Fig. 2 shows each element of the above-mentioned input position detection device 100 of exemplary embodiment according to the present invention.This
Outside, Fig. 3 A are the diagrams for the finger touch input and electronic pen input for showing exemplary embodiment according to the present invention.Fig. 3 B are
The letter being shown as between the finger touch input of the input method of exemplary embodiment according to the present invention and electronic pen input
Number intensity difference diagram.
With reference to Fig. 2, touch sensor 145 includes the grid that multiple horizontal pickup wires intersect at a right angle with multiple vertical pickup wires
Lattice type of touch sensor.Receiving unit 141 is arranged in transverse axis, and transmitting element 143 is arranged in the longitudinal axis.Controller 160 can
Changed by using switch control by the operation change of transmitting element 143 to receiving unit 141 or by the operation of receiving unit 141
Change to transmitting element 143.In addition, controller 160 can selectively detect finger touch input and electronics according to the setting of user
Pen input.When indicating that controller 160 only detects electronic pen input in the setting in user, all biographies of touch sensor are configured
Sensor line can work as receiving unit 141.As shown in Figure 1, touch sensor 145 includes receiving unit 141 and transmitting element
143, but it is without being limited thereto.Receiving unit 141 and transmitting element 143 can be configured in separate modules.
Hereinafter, if there is finger touch input as shown in Figure 3A, then the member of Fig. 2 of detection input position is performed
The operation of part is as follows.
Controller 160 controls the processing that electric energy is supplied to wave filter 150 by power supply unit 130.Then, wave filter
150 using electric energy production predeterminated frequency electric signal and the electric signal of generation is supplied to transmitting element 143.By the processing,
Uniform electric field is formed between transmitting element 143 and receiving unit 141.Here, electric signal is sent to reception by transmitting element 143
Unit 141.Before finger touch, electric signal keeps the preset value of the constant intensity of charge.If it produces in such a state
Finger contact input 310 is given birth to, then charge leakage occurs for the point in contact or charge will decline.Here, power supply unit 130 passes through
Electric energy is supplied to vertical pickup wire and horizontal pickup wire using switch, this enables controller 160 to check each coordinate in real time
The intensity of the charge of axis is declined with detecting whether to occur charge leakage or charge.Detection in this way, controller 160 can determine
Finger touch input 310 has generated.In addition, controller 160 can the transmitting element 143 based on configuration grate type touch sensor
With the coordinate position of receiving unit 141, examined by verifying the position of the intensity of electric signal reduced by finger touch input 310
Survey input position.That is, the circuit measuring charge positioned at the every nook and cranny of panel decline and will send information to controller for
It is later determined that touch the processing of the X-coordinate and Y-coordinate of activation.
Therefore, when multiple finger touch inputs 310 occur, controller 160 can also identify finger in the same way
The generation of touch input 310 and their input position.Meanwhile controller 160 can identify passive touch-control in the same way
The generation of pen input simultaneously detects its input position.Even if it is defeated that finger touch occurs together in input position detection device 100
Enter the input of 310 and passive stylus, controller 160 also performs detection operation.
Next, when there are during the input of the electronic pen of Fig. 3 A, the operation of the element of Fig. 2 of execution detection input position is such as
Under.
It should be noted that general active electronic pen uses electromagnetic induction, however, the electronic pen 200 of the present invention sends electric field
Active electronic pen.Since the location detecting apparatus 100 of the present invention is not equipped with using with reference to the active electronic pen 200 of the present invention
Magnetic sheet, therefore the active electronic pen of the present invention includes generating the individual power supply unit of electric field.That is, according to the disclosure,
Active electronic pen may include built-in power.
With reference to Fig. 2, electronic pen 200 forms electric field between the receiving unit 141 of location detecting apparatus 100.Here, do not examine
Whether uniform consider the electric field generated by active electronic pen.Electronic pen 200 generates electric signal using electric field and sends electric signal
To receiving unit 141.That is, the change of electric field generates electric signal.Controller 160 controls wave filter 150 so that electric signal can have
The value of specific frequency.
The electric signal received by receiving unit 141 from transmitting element 143 keeps the peak value of pre-set constant amplitude.
In other words, receiving unit 141 is received while the peak value of amplitude is kept constant in location detecting apparatus 100
Portion's electric signal.When there are during electronic pen input 320, electric signal is sent to reception list by both transmitting element 143 and electronic pen 200
Member 141.Receiving unit 141 receives electric signal from electronic pen 200.Electronic pen 200 can be driven or passed through certainly by built-in power unit
External power supply drives.For example, external power supply can be provided by the USB port, RFID or NFC of computer.Electronics in the present invention
Pen includes RF transmitters and antenna.RF transmitters generate electric field, the radiogenic electric field of antenna.Electronic pen may include nib, pressure
Force snesor, power supply unit and button.Therefore, receiving unit 141 receives the electric signal sent by transmitting element 143（Inside letter
Number）With the electric signal sent by electronic pen 200（External signal）The two.
As a result, when there are during electronic pen input 320, the intensity of the electric signal received by receiving unit 141 is big
The intensity of the electric signal received in the case of no electronic pen input 320 by receiving unit 141.This is the opposite of following phenomenon
Phenomenon：The intensity of the electric signal received by receiving unit 141 become than there are during finger touch input 310 by receiving unit 141
The intensity of the electric signal of reception is small.Even if there are during multiple electronic pens input 320, controller 160 can also be with same side
Formula learns the generation of multiple electronic pen inputs 320 and multiple input position.
In addition, in the presence of finger touch input 310 and electronic pen input 320 both, controller 160 can pass through detection
Each input is detected by the intensity of 141 received signal of receiving unit.When the electricity that any point in receiving unit 141 receives
When the intensity of signal is less than the intensity of the internal signal sent by transmitting element 143, controller 160 determines finger touch input
310 are present in the point.On the other hand, the intensity of the electric signal received when any point in receiving unit 141 is more than by sending out
When sending the intensity of the internal signal of the transmission of unit 143, controller 160 determines that electronic pen input 320 is present in the point.
Therefore, even if when multiple input occurs, controller 160 also can detect each input and their input position.
Meanwhile when the intensity of electric signal of the intensity with being received by receiving unit 141 of the internal signal sent by transmitting element 143 is identical
When, controller 160 is not it is believed that finger touch input 310 and electronic pen input 320 occur.
In addition, the controllable configuration receiving unit 141 of grate type touch sensor of controller 160 and transmitting element 143
Function.In addition, controller 160 can selectively detect finger touch input 310 and electronic pen input according to the setting of user
320.When controller 160 only detects electronic pen input according to the setting of user, the pickup wire for configuring touch sensor can be only
It works as receiving unit 141.In this case, the internal signal sent by transmitting element 143 is not present, this is because not
Exist that serve as the pickup wire of transmitting element 141.Therefore, when receiving unit 141 receives the electric signal for being better than preset strength,
Controller can detect input position rather than perform by the intensity of internal signal with by the strong of 141 received signal of receiving unit
Spend the process being compared.

Fig. 2 shows the configuration that receiving unit 141 and transmitting element 143 are arranged with line type.Selectively, from transmitting element
143 signals sent can be received by a plurality of sense wire by receiving unit 141.In this case, receiving unit 141 can pass through
The signal sent by a plurality of sense wire selectively or is sequentially detected using switch.In addition, by wave filter 150, send
Unit 143, which can only send desired frequency signal or receiving unit 141, can only receive desired frequency signal.Meanwhile when connecing
When receipts unit 141 detects the signal of specific position, receiving unit 141 can be set around the specific position for detecting signal
Adjacent domain.Receiving unit 141 can be also distinguished respectively outside operation and the adjacent domain of the signal detection inside adjacent domain
The operation of signal detection.
Fig. 5 A and Fig. 5 B are showing for the adjacent domain for the setting input position for showing exemplary embodiment according to the present invention
Figure.Fig. 6 is the signal detection inside the adjacent domain for showing exemplary embodiment according to the present invention and outside adjacent domain
The flow chart of operation.
Fig. 5 A and Fig. 5 B show a plurality of pickup wire horizontally and vertically arranged.Every pickup wire can be by switching and filtering
Ripple device is connected to receiving unit 141 and transmitting element 143.As shown in the figure, the pickup wire of transverse axis is expressed as R0 to R9, the longitudinal axis
Pickup wire is expressed as C0 to C9.Here, suppose that the quantity of pickup wire horizontally and vertically is 10, but it is without being limited thereto.
With reference to Fig. 6, controller 160 determines whether to detect input position (610).Even if in multiple position detections to defeated
Enter, in proximity detection place, among position that also can be by detecting signal close to the position at midpoint or by detecting
The position of signal with most intensity determines input position.For example, controller can determine in the pickup wire with transverse axis R6
510 are put accordingly with the pickup wire of longitudinal axis C5 to input.In this case, as shown in Figure 5A, point 510 is represented by
（R6, C5）.
When detecting input position, controller 160 sets the adjacent domain (620) around input position.It is for example, neighbouring
Adjacent domain can be respectively set in two pickup wires of input position.That is, with the pickup wire of transverse axis R4 to R8 and vertical
The corresponding region of pickup wire of axis C3 to C7 may be configured as adjacent domain.As exemplary embodiment of the present invention, Fig. 5 A show
Go out the adjacent domain 520 of input position 510.
Simultaneously, it is contemplated that the moving direction of input position determines adjacent domain.For example, as shown in Figure 5 B, it can be according to defeated
The moving direction for entering position sets wider adjacent domain 550.Once controller determines to input in point 510, then can be not
Be point 510 another place detect input.In this case, it is contemplated that previously detection and next detection determine input position
Direction.Fig. 5 B show that controller determines（R5, C6）New input position occurs.If new input position is point 530,
User's input is moved to a little 530 from point 510.In this case, according to from point 510 to point 530 direction, when as shown in Figure 5 B
During the adjacent domain of set-point 530, controller can set 540 broader adjacent domain 550 of neighbour near field.That is, without considering
In the case of moving direction, adjacent domain can be adjacent to two pickup wires of input position.On the other hand, considering to move
In the case of the mobile route of dynamic direction or estimation, adjacent domain can be adjacent to three pickup wires of input position.Figure
5B shown in the case of the moving direction without considering input position, the adjacent domain 540 of controller set-point 530.Fig. 5 B show
Go out in the case where considering the mobile route of estimation of input position, the adjacent domain 550 of controller set-point 530.Fig. 5 B show
Go out increases an other pickup wire for the moving direction of input position, but without being limited thereto.For example, two can be increased separately
Outer pickup wire.It meanwhile can placement sensor line in this way：Positioned at the opposite side of the moving direction of input position
The quantity of pickup wire can reduce.
When there is provided after adjacent domain, controller 160, which can be directed to inside adjacent domain, increases detection frequency (630).For example,
When touch sensor 145 includes a plurality of sense wire, the sense period of the sense wire inside adjacent domain can be reduced.Therefore, may be used
Increase the detection speed of input position inside adjacent domain.
Controller 160, which can be directed to outside adjacent domain, reduces detection frequency (640).For example, when touch sensor 145 includes
During a plurality of sense wire, the sense period or selectively of sense wire outside adjacent domain can be increased, can be omitted outside adjacent domain
The sensing of some sense wires in portion.For example, in the state of adjacent domain is not provided with, input can be detected in this way：
All sense wires are detected once, and subsequent all sense wires are detected again.In this case, set adjacent domain it
Afterwards, input can be detected in this way：After all sense wires inside adjacent domain are detected three times, adjacent domain
External sense wire is detected once.Omitting the sensing of some sense wires outside adjacent domain may include：It only senses neighbouring
A line in two lines.Meanwhile when there are two or more inputs being not adjacent to each other, except each input position
Remaining area outside adjacent domain inside can be confirmed as outside adjacent domain.
Controller can detect input as described above until detecting the change of input position based on default adjacent domain.
Controller can increase the inside and outside detection frequency of adjacent domain respectively.Controller again determines whether to disappear in the predetermined time
Input position (650) is detected afterwards.In this case, when input position is not detected, controller is there is no neighbouring
Cancel the setting of adjacent domain in the state of region and detect input position (660).On the other hand, when detecting input position
When, controller can determine whether input position changes (670).When input position does not change, performed based on default adjacent domain
Sensing.On the other hand, when input position changes, adjacent domain is set based on new input position, and based on newly-installed
Adjacent domain detects input position.
